Abstract

The cross arm mechanism for a pushbutton tuner includes an arm plate rotatably supporting a frequency setting plate, a plate spring mounted on the arm plate for locking the frequency setting plate from its circumference, and first and second pins uniting the arm plate and the plate spring together. The mechanism is particularly characterized in employment the first and second pins which are different in height.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows: 
     
       1. A cross arm mechanism in a pushbutton tuner which comprises: an arm plate rotatably supporting a frequency setting plate;   a plate spring mounted on said arm plate for locking said frequency setting plate from the circumference thereof; and   first and second pins uniting said arm plate with said plate spring, said pins being different in height,   wherein said pins are a pair of tongues made by partly cutting an end portion of said arm plate, said plate spring being formed at one end portion thereof with a pair of bores engaging said tongues.   
     
     
       2. A cross arm mechanism as set forth in claim 1 further including a guide pin fixed to said arm plate by caulking fixture and projecting downward from the lower face of the arm plate.
